A liquid inlet pipe 101 and a liquid outlet pipe 102 are connected to the working box 1, and the liquid outlet pipe 102 is connected to the boiler body. When the device is in use, the boiler flue gas can enter the heat exchange pipe 3 through the conical connector 4 located at the bottom, and continue to be guided through the conical connector 4 located at the top, so as to preheat the liquid inside the working box 1. After the preheating is completed, the liquid is guided to the inside of the boiler body through the liquid outlet pipe 102, and the insulation treatment is performed on the outside of the device through the insulation layer 2. In this device, the use effect of the boiler body is greatly improved, and the heat of the boiler body flue gas can be reused, which is more environmentally friendly and efficient.
